I SHOULD buy a lot of stuff for brewing. Unfortunately I'm often reminded that my "beer gig" is getting out of control! That plus I have too many hobbies.
Thanks for the advice. I'm pretty convinced that the excess of carbonation/primer sugar is the reason but I was hoping others could verify. Also, the metallic flavor never dissipated in the brew I did back in June. Thankfully the more recent batch is drinkable.
